Description

Continuous improvement has become synonymous with the Six Sigma process, where cost reduction and quality improvement have led to greater market share and profits. Leading organizations in diverse industries have begun to further deploy Six Sigma outside of manufacturing to maximize its benefits.

This comprehensive training tool and implementation guide delineates how Six Sigma methods can be applied to processes within numerous functional areas of the organization and in diverse industries to achieve strategic and operational business excellence. It presents step-by-step techniques and flow diagrams for integrating Six Sigma as best practices into business development and management. It provides a seamless integration of Six Sigma statistical methodologies that help businesses execute their strategic plans and track both their short- and long-term strategic progress within various areas of their business. Statistical methods employed in Six Sigma are thoroughly explained and their implementation, supported by examples and exercises, is demonstrated via Minitab 14, a popular statistical software package. Six Sigma Best Practices is an ideal text for executive training in planning and leading Six Sigma programs, for Yellow, Green and Black Belt certification programs, for college courses and as a desk reference for practitioners and consultants.

Key Features

  • Illustrates how Six Sigma can be applied and implemented within numerous areas of an organization to achieve business process excellence that will lead to sustainable growth in profits and market share
  • Presents Six Sigma concepts in common business terms as well as in applied statistics, where the benefits of the tool are better understood, and process centering, which is a prerequisite to Six Sigma implementation
  • Details the measure phase of the DMAIC process extensively and develops the relationship between operational and financial metrics to show the biggest leverage points in an organization
  • Demonstrates the implementation of statistical methods employed in Six Sigma via Minitab 14 software
  • Covers project selection, planning, team development and management and shows how to develop and understand a project summary, which is critical to effective Six Sigma implementation

Reviews

“Unlike other texts on the subject, Dr. Kumar’s book covers six sigma from the perspective of a practitioner working in the trenches of a large manufacturer, coping with the realities of training large numbers of people and showing how quality results improve the bottom line and product reputation. This is important: too many authors take a glossy, generalized approach to six sigma, emphasizing its benefits without giving a detailed map showing how to get there, create a totally supportive culture, and stay there for the long term in a competitive global environment. Dr. Kumar has all the statistics, but carefully leads the reader through them in plain English and with plenty of detailed examples. It is easy to follow, realistic, and delivers a true sense of what one meets in practice on the shop floor.”
